BAG-HOLDING MEANS FOR NOZZLES.

Application filed April 8,

To all whom it may concern:

Be it known that I PRATT E. TRACY, a citizen of the United tatea'and a resident of Toledo, in the county of Lucas and State of Ohio, have made an invention appertaining to Bag-Holding Means for Nozzles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to means for attaching dust collecting bags to the discharge nozzles of vacuum cleaners, and particularly to the class of cleaners em loying paper or temporary dust collecting ags.

In the use of nozzles of the character described, it is customary to attach the dust receiving ba s thereto by slipping the bag mouth over-51c nozzle and then binding the bag thereto by an elastic band. With this means it is difficult to properly locate the elastic band on the nozzle and retain it in bag holding position, and it is the object of this invention to provide the discharge nozzle with means which will not only serve to locate the elastic band in bag holding position and to retain it in such position on the nozzle, but which will also facilitate the movement of the holding band to bag filling position.

- The invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying rawings, in which,-

Figure 1 is a side elevation of one form of vacuum cleaner embodying the invention, with "the dust collecting ba and the enclosing bagtherefor partly bro en away.

Fi 2 is an enlarged bottom view of a nozzle em odying the invention with the band in bag holding position thereon, and Fig 3 is an enlarged side elevationIof the nozzle,

with the temporary dust collecting bag andthe enclosing cover in position thereon, with parts broken away-. a

Referring to the drawings, -1 designates the discharge nozzle of a vacuum cleaner, which is adapted to have its inner end slipped'over and engaged tothe discharge Specification of Letters Patent.

conduit of a vacuum cleaner, by a bayonet joint connection, or 'in any other suitable manner. The nozzle preferably has its discharge end cut away at its bottom portion to provlde an upper directing lip 2. The nozzle 1 is provided at spaced intervals therearound with longitudinally extending fingers 3 in the present instance, two in number which are fixed at their rear ends to the rear end portion of the nozzle and ha e their free ends extending longitudinally of the nozzle towards its outer end. Each of these fingers is provided at its outer end with an inwardly disposed recess 4 forming a seat having an elastic band 5, which preferably eomprlses a coiled spring wire.

The dust collecting bag 6, which may be of paper or other sultable material, is provided adjacent to its upper edge in the forward end thereof with a portion 7 forming a mouth for receiving the nozzle 1. The portion 7 is adapted to be forced over the discharge end of the nozzle under the free ends of the fingers 3 and in position for the elastic band 5 to yieldingly gri and hold said tubular portion to the nozz e and also to force the fingers 3 in gripping engagement therewith when the band is seated in the notches or recesses provided therefor in the fingers, as shown. When a bag mouth is being placed over or removed from the nozzle the holding band 5 is moved to the inner end of the nozzle out of'bag holding position, and when a bag has been placed in engagement with the nozzle the band is moved outwardly on the nozzle up the inclined portions of the fingers 3 and into the holding recessesthereof.

The outer or protecting bag or cover 8,

which is customarily used in connection. with bags of the temporary type, has a noz-- zle receiving tube portion 9 turned into the bag and adapted to be fixed to the inner end portion of the nozzle by a string, wire or band 10. His evident that in placing a dust collecting bag 6 onto the nozzle 1 or Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is,

1. The combination with a discharge nozzle for entering the mouths of dust collect ing bags of vacuum cleaners of an elastic band encircling the nozzle and movable lengthwise thereof for yieldingly holding a bag in position thereon, and means carried by the nozzle for movement relative thereto and coacting with the band to yieldingly retain it in bag holding position.-

2. The combination with a discharge nozzle adapted to be inserted into the mouth of a bag of spring fingers fixed to the nozzle and having their free ends projecting toward the outer end of the nozzle, and an elastic band encircling the nozzle and fingers and cooperating with the latter to hold a bag in position on the nozzle.

3. The combination with a discharge nozzle adapted to enter the mouth of a bag, of fingers fixed to the nozzle in spaced relation therearound and having their free ends projected toward the outer end of the nozzle and each provided in its outer side with a.

over said fingers to and from bag holding position and to seat in the notches in the fingers when in bag holding position.

4. The combination with the discharge nozzle of a vacuum cleaner and a dust collecting bag having a tubular mouth portion removably fitting over'said nozzle, of spring fingers disposed in spaced relation around the nozzle with their rear ends fixed to the inner end portion of the nozzle and their outer ends projecting lengthwise of the nozzle towards its. outer end and over a portion of a bag engaged with the nozzle, said fingers having band receiving notches in their outer end portions, and an elastic band encircling the nozzle and adapted to seat in the finger notches in bag holding relation and to be moved rearwardly from said notches out of bag holding position.

In testimony whereof I have hereunto signed my name to this specification.

PRATT E. TRACY.
